Abstract: The invention relates to a method of making a centring ring in the clamp leg of a U-shaped sheet-metal nut by punching out a round plain sheet (3) and a likewise round inner sheet (14) and subsequently obliquely bending the centring ring (15) produced in this way, the punched-out centring ring remaining connected via a narrow web (4) to the sheet-metal strip forming the clamp leg. In order to allow the centring ring to spring back easily into the cut-out of the sheet-metal strip, the punched-out plane sheet (3) is first of all pressed down to just below the sheet-metal strip (1) and deep-drawn in the form of a hemispherical cup before the centring ring (15) is punched out. The bent-down web (4) is then pushed up into the plane of the sheet-metal strip again, the gap (12) obtained during the deep-drawing of the hemispherical cup (14), between the outer circumference of the plane sheet (3) and the inner edge (11) of the cut-out of the sheet-metal strip (1) being greater than the stretch of the centring ring (15) during the pressing up of the bent-down web (4) into the plane of the sheet-metal strip.

Abstract: The insulative support bracket (21) of a surge arrester sincludes a concentric annular concavity (50 or 57) formed at one or both ends of a bolt hole (53). A washer (25), when pressed concentrically to the concavity (50 or 57), contacts the insulative bracket only, at least initially, at surfaces adjacent the outer edge of the washer (25). An annular convexity (49), surrounding the concavity (50 or 57), wil mate with the central portion of an external tooth lockwasher (26) to prevent the full penetration of the teeth of the lockwasher into the insulative bracket (21). The ability of the insulative bracket to withstand the mechanical forces transmitted to it by the washers (25,26) is thereby enhanced. The concavity (50) may be formed either in a surface of the insulative bracket (21) or in a surface of the washer (25).

Abstract: Image processing apparatus with a colour saturation controller for processing a colour image signal to be printed derives colour difference signals (61) from an incoming colour image signal, detects (62) a minimum difference value between an allowable dynamic range of colour difference signals and the derived colour difference signals, and generates (63) a coefficient value based on the detected minimum difference value. The levels of the derived colour difference signals are corrected by multiplying (66) the generated coefficient value and the colour difference signals. The dynamic range of the input colour difference signals is extended by such multiplication within a range not causing any overflow, and the colour saturation is directly corrected without changing the colour phase of the image signal.

Abstract: The instant invention is a process for the removal of hydrogen-containing silane impurities from organosilanes with similar boiling points. In the instant invention, the hydrogen-containing silane is reacted with a hydrogen halide to replace the hydrogen on the silane with a halide and create a modified silane. The substitution of the heavier halide for the hydrogen, increases the boiling point of the modified silane. This increase in boiling point facilitates separation by distillation of the modified silane impurity from the desired organosilanes.

Abstract: In a method for manufacturing a device having a film of high temperature superconductor, a copper substrate is used in the electrophoretic deposition as a cathode on which fine powders of superconductor should be deposited, and the fine powders deposited on the substrate are fired in the conditions that they are sintered partially. 
     In other methods for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic deposition is formed on a substrate, and a minute pattern of fine powders is deposited according to the pattern of the cathode. Then, the fine powders are fired to form a superconductor film. Such a desired pattern of the cathode is formed by the patterning of a film of an electrically insulating substrate. Such a desired pattern of the cathode is also formed by the patterning of an electrically insulating material, applied to an electrically conductive substrate. 
     In a further method for manufacturing such a device, a desired minute pattern of electrically conductive material as a cathode in the electrophoretic   deposition is formed on a substrate, while another pattern of electrically conductive material as an anode is formed on the same substrate near the former pattern so as to keep a constant distance. The fine powders deposited on the former pattern are fired to form a superconductor film.

Abstract: The amplitude of the hysteresis of the circuit is determined principally by the intensity of the current (Io) produced by a generator by means of a "band gap" reference voltage, an internal resistance of the circuit, and the resistances (Rx and Ry) connected to the emitters of the input-stage transistors (Q1, Q2), enabling a high degree of precision to be achieved. The inputs of the circuit are defined by the bases of the input-stage transistors (Q1, Q2) and therefore have high impedance. 
     The preferred application is for forming interface circuits for sensors to be fitted in motor vehicles.

Abstract: The amount of degradation converted into a fuzzy qualitative value is found on the basis of state data sensed by sensors (1a, 1b and 1c) and degradation data. The value of a parameter changed by the amount of degradation is represented by a fuzzy qualitative value. In addition, the state data is converted into a fuzzy qualitative value, and it is judged by the value whether or not a fault exists. As a result, if a fault exists, fault diagnosis is made utilizing as an initial value the value of the parameter changed by the amount of degradation, and the causes of the fault are specified by comparing the result of the diagnosis with the state data converted into the fuzzy qualitative value. The causes of the fault specified are repaired by operating corresponding actuators (6a, 6b and 6c). Since the causes of the fault are specified while handling the fuzzy qualitative value, the causes of the fault can be specified more precisely. Accordingly, it is possible to achieve an image forming apparatus in which autonomy is high and labor saving of repair work is realized.
